Life Behind the Shadow of the Cross - A Syllabus includes understandings gained after McCullough's personal anguish of losing a loved one, experiencing a very traumatic divorce, as well as other impacting occurrences. Her tragedies lead her to nearly commit one of the worst sins of all: the attempt to take her own life. McCullough's experience with an angel of God on that fateful night in 1977 after she thought she'd lost everything leads her through the painful but wondrous process of better understanding herself, her God, the world, and her role in it to best serve Jesus Christ and mankind. The endurance of much misunderstanding from others in her efforts to know God has also largely contributed to the writing of this work. McCullough, who served as a teacher, deaconness, devotional leader, evangelist, senior elder and prophetess, gives first hand accounts of her salvation through knowledge gleaned through her studies, receiving direct revelation from Jesus Christ, as well as quotes from the greatest book of all, The Bible, King James Version.
